After Ursula arrives at Blackens Gate, she soon realizes that humans are not only servants but also slaves to the wolves who live there. When she learns what her fate will be, she takes the help of a half-human wolf to try and save her life.

Henry is a half-human wolf that hates the way the humans are treated in the only home he has ever known. One woman unexplainably keeps his attention and he decides that though he cannot save everyone, he must try and save her.

Henry and Ursula must trust each other for their plan to work, and they each have something to lose. Ursula knows trusting Henry could be a trap, but she has no other options if she wants to live. If Henry is caught helping Ursula, he will be labeled a traitor and killed. When their friends come up with a plan for them both to find happiness, trust is the only way it might lead to love.

Ms. Barnette has created a world of wolves that is different from most romances. In this world, the wolves are to be feared except for a select few. While it was different, it was an interesting and enjoyable read. Henry and Ursula were endearing, each with their own inner battles, and I loved watching their romance bloom. The supporting characters made me want to read book one and learn more about the Canis Clan.
